1‐Phospha‐1,2,3‐butatriene

Abstract
The first phosphacumulenes of type 1 have been synthesized from dichloro(2,4,6‐tri‐tert‐butylphenyl)phosphane and lithioallenes. According to an X‐ray structure analysis, the unit in 1a, R′ = R″ = Ph, is linear. In the case of 1b, with Me and SiMe3 as substituents (R′, R″), the expected E/Z isomer could be isolated. equation image
